A woman died early Thursday morning in a car crash on Interstate 65 at the Outer Loop eastbound exit ramp.

The woman, who the coroner identified as Donna Kirk, 72, was driving southbound on I-65 when she exited onto the ramp of the Outer Loop eastbound and lost control of the car. She hit a concrete wall, drove off the roadway and was ejected from her vehicle, according to an email from Louisville Metro Police spokesman Dwight Mitchell.

Officials pronounced the woman dead at the scene. It's unclear why she lost control of the vehicle, Mitchell said.

No other cars were involved in the crash. The LMPD Traffic Unit continues to investigate.
